Energy Requirements of a Multi-Sensor Based Demand Control Ventilation System In Residential Buildings | 2010 | English
In Korea, in 2006, the building regulation was revised to apply 0.7 ACH (Air Change Rate) ventilation systems to improve indoor air quality in residential apartment housing.
Robustness and True Performance of Demand Controlled Ventilation in Educational Buildings – Review and Needs for Future Development | 2010 | English
Although theoretical studies show that energy use for ventilation purposes can be reduced by more than 50% with DCV compared to CAV, evaluation of real energy use demonstrates that this potential is seldom met.
When it comes to natural ventilation performance for large space cooling during summer time or intermediate seasons, double skin facade(DSF) integrated with cross ventilation(CV) exhibits more energy efficiency than single-side ventilated DSF.
Building simulation on utilization of roof window in detached house by using cross-ventilation | 2010 | English
The effects of roof window on ventilation flow rates and reduction of cooling loads in densely populated areas were investigated by using building simulations.
Velocity Measurement Inside and Outside a Cross-Ventilated Building by Means of PIV | 2010 | English
Cross-ventilation is regarded to be beneficial control method to obtain thermal comfort in a hot summer without using mechanical devices. Since it is complicated flow phenomenon, details of flow characteristics have not been sufficiently known.
Analysis on CO2 Emissions Reduction Effect of Zero Energy Multi-famiy Housing to cope with UNFCCC | 2010 | English
Korean government established a target to reduce greenhouse gas (“GHG”) emissions to 30% by 2020 to cope with the United Nations Framework Convention on Climate Change (UNFCCC) and secure its national competitiveness, and prepared a roadmap to dev
Reduction of infiltration in the Equinox House, a residence under construction in Urbana Illinois, has been characterized through a series of blower tests as different joints and seams in the building were sealed.
The objective of this paper is to present a new method for estimating effective flow areas not only in the external wall of a house but also in the internal walls between rooms using only one type of tracer gas.
Museum showcases represent a peculiar confined space were ventilation and indoor climate conditions play an important role.
Implementation of measurement and quality frameworks in the French regulation for achieving airtight envelopes | 2010 | English
It is foreseen that the 2012 version of the French regulation will include a minimum requirement for the envelope airtightness of residential buildings, with two options to justify its treatment: a) measurement at commissioning or b) adoption of a
Influence of natural ventilation usage on cooling energy consumption and cooling capacity of an air conditioner | 2010 | English
In Japan, natural ventilation through large openings has been used for cooling in summer and medium season. However, air conditioner has become popular recently, because it is hot and humid in summer in most parts of Japan.
The influence of stochastic modeling of window actions on simulated summer comfort in office buildings | 2010 | English
In this study, an attempt is made to define building design variables for a medium-sized office building with individual office cells in order to provide sufficient summer comfort without active cooling in a moderate climate.
Fungal Growth Prediction on Building Materials by Reaction-Diffusion Model Coupled with Heat and Moisture transfer | 2010 | English
A mathematical model that reproduces fungal proliferation and morphological colony formation was developed on the basis of a reaction diffusion modeling approach.
In this paper, we created the CFD parts of four-way cassette type outlets for predicting easily the thermal environment of an office with packaged unit air-conditioning systems.
The paper presents a study on the thermal behavior of a solar greenhouse set against one apartment of a residential eco-sustainable building in a temperate climate.
Modelling wind driven airflow rate with CFD and verification of approximation formulas based on wind pressure coefficients | 2010 | English
An isothermal CFD study was made of a building perpendicular to the wind direction. The building was modelled with a closed façade, and consecutively with one and multiple openings.
Development of Zonal Model for Predicting Temperature Distribution inside an Office Room with Hybrid Air-conditioning System | 2010 | English
Recently, the hybrid air-conditioning system that used natural ventilation together with a mechanical air-conditioning was proposed.
Effect of Intermittent Operation of Ventilation System on Indoor Air Quality in Apartments | 2010 | English
This study analyzed the effect of intermittent operation of ventilation system on changes of indoor air pollutants' levels through field measurements.
Influence of the Configuration of Consecutive Street Canyons and Atmospheric Stability | 2010 | English
This research, based on Computational Fluid Dynamics (CFD) analysis, focuses on the wind characteristics and the ventilation performance in the consecutive street canyons produced by various building complex configurations.
